Assume that you have a sample of n, -7, with the sample mean X, 41, and a sample standard deviation of S, -4, and you have an independent sample of ₂-12 from another population with a sample mean of X₂-34, and the sample standard deviation S₂ 8. Construct a 95% confidence interval estimate of the population mean difference between u, and p. Assume that the two population variances are equal SP₂ (Round to two decimal places as needed.)
